Hi Drew,
I've not seen anything for this part.
From a 10 second glance at the data sheet I see it's capable of
ADC / GPIO on each pin. If you plan to support that functionality
at somepoint make sure to define dt bindings and similar to specify
which channels are enabled and dynamically create the iio_chan_spec
array to match. It can be a bit ugly to retrofit later.
Oh. It does daisy chaining as well. That is always fun to support
though I guess you may well not have it wired up to do that.
Oversampling as well - though that looks nice and simple for once.
